LOCK.

Specification of Letters Patent.

Patented Jan. 25, 1916.

Application filed December 4, 1913. Serial No. 804,638.

To all whom it may come mi Be it known that I, ALBERT A. PAGE, a citizen of the United States, residing in the town of East Haven, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Locks, of which the. following is a. full, clear, and exact description.

This invention relates to looks, and more particularly to the locks for the communicating doors of hotel rooms.

The primary object of the invention is to provide a lock in which the two customary independent thumb bolts operable from the respective sides of the door may be retracted simultaneously with a key bolt, which is only operable by a chambenmaid, bell boy, or other authorized person, in possession of a proper key. The door may be locked by the key bolt, so that the manipulation of either or both of the thumb bolts will be of no eii'ect in opening the door, and when the key bolt is retracted by an authorized person each thumb bolt which isin protracted position will be retracted simultaneously with the key bolt, so that the opening of the cloor by such person will be'facilitated. I

The invention also aims to provide simple,

efiective mechanism, applicable to looks of different types, whereby two or more tumbler controlled bolts may be simultaneously retracted; to provide improved tumbler mechanism for the thumb bolts of a communicating door lock, or for other boltsha-ving the same general location relative to each other; and to improve the general construction and operation of devicesofthe class to which my invention relates.

To these and other ends, the invention consists in the novel features and combinations of parts :to be hereinatterdescribed and claimed. Y

In the accompanying drawings, Figure 1 is an elevation of a lock embodying my improvements, with the cap plate removed, the thumb bolts and key bolt being in retracted position; Fig. 2 is an elevation of the lower part of the lock, showing one of the thumb boltsprotracted; Fig. 3 is a similar view, with one thumb bolt vomitted and the other in protracted position; Fig- 4 is an elevation of the main part of the lock, showing the key bolt and one of the thumb bolts protracted, the other thumb bolt being omitted; Fig- 5 is a viewsiinilar'to Fig. 4;, showing both thumb bolts partly retracted by the partial retraction of the key bolt; Fig. 6 is a section on line 66 of Fig. 1; Fig. 7 shows one of the thumb bolts in detail; Fig. 8 shows the other thumb bolt in detail; Fig. 9 shows the thumb bolt tumbler in detail; and Fig. 10 is a detail of one of the thumb bolt hubs.

Referring to the drawings, 20 is a case of usual type, and 21 and 22 are independent thumb bolts. These thumb bolts have the customary relation to each other in so .far as their shank portions extend alongside each other, while their heads are: ofiset vertically. The bolt 21 is adapted to be protracted and retracted by a thumb bolt hub 23, and the bolt 22 is adapted to be pro tracted and retracted by the hub 24:. Referring to Figs. 7 and 8, it will be noted that the shanks 21, 22 of the respective bolts are so formed as to create between said bolts a recess for a tumbler 25 common to said bolts. This tumbler is pivoted in the case on a post 26, and its main portion is interposed between the shanks 21*, 22, and is provided with a lug 27 at its upper edge, adapted to cooperate with stumps 21", 22 projecting inward from the shanks'of the respective bolts. At its extremity, the tumbler 25 is provided with a tail or sweep 28, adapted to be engaged by both hubs 23 and 24., so that said tumbler may be released from engagement with the bolt stumps or fences 21 ,22, by actuation of either hub. The hub 23 is provided with a nose 23 (Fig. 10) to cooperate with the tumbler sweep 28, and with a roll-back arm23 to cooperate with the roll-back notch 21 of the bolt 21, and the hub 24 is similarly provided with a nose 24 to cooperate with the sweep 28 and with a roll-back arm 24 to cooperate with the roll-back notch 22 of the bolt 22. The

stumps or fences 21 22 extend upward from the upper edges of the respective bolt shanks to a certain extent for a purpose which will hereinafter appear.

Above the thumb bolts 21, 22 is a key bolt 29 adapted to be operated by a key inserted in a keyway 30, open at opposite sides of the case. This bolt is provided with a stump or fence 31, with which cooperates a. tumbler 32, pivoted on a post 33. In practice, the bolt 29 will have a certain number of tumblers in addition to the tumbler 32, but this. teatare :need. not he. discussed in as follows :NVhen' the partsare in the are formed as elbow levers, and one armof each lever is adapted to engage. an arm of the other lever. a

Secured to the shank of the key bolt 29 is a movable thumb bolt; retractingimember,

preferably comprising a lever 37 ,pivoted on the bolt29 at 38 This lever 37 is acted on byv a spring-39 whic'hurges the free end of said leverin a downward direction toward the thumb bolts. The lever 37*is suitably formedto clear the tumblers-25 and 32 in the operations hereinafter described, and its lowerv free end isprovided with a lateral projection 40, adapted to engage either or both of the tumbler stumps 21 22 of the respective thumb bolts.

' The operation of the lock is substantially position shown in Fig. 1, the'thumb bolts 21, 22 may be independently operated by the hubs 23, 24 respectively. When it is desired to prevent. guests orothersfrom' opening the door from either side, the key bolt 29 i'sthrown, from either side of the door, by the maid or other possessor of the proper key. The manipulation'of the thumb bolts will then be of no effect in opening the door. Supposing, now, that-when themaid, or other authorized person, desires tounlock-the door, both of the thumb bolts are in protracted position, the key" bolt in being retracted, will retractboth thumb bolts. This is due to the fact that when the key bolt isprotracted, the extremity 40 of the lever-37, will beheld by the spring 39 in line with the tumbler stumps 2 1 22 -so that as the lever 37- is moved rearward ly by re-.

. traction of the-key bolt, it will retraet'both thumbbolts; The release ofthethumb bolts for this retracting 'mevem'ent is produced by thetumbler'32' oi 'the key bolt whieh, in being-raisedby the key,- is so'actuatedthat its arm 35 contacts with and; shifts the arm 36 of tumbler-'35 to r'eleasethe latter tumbler.

- In otherwords, when the tumbler mechanism of bolt29'is released, the tumbler of the thumb bolts is likewise released, so that as the. key bolt is retracted, the thumb boltretracting member 37 may freely retract the thumb bolts. When the key bolt isprojected,

V the spring 39 ispermitted to act freely'on the lever 37, and hold it in horizontal alinement with the tumblerstumps of the thumb bolts, but when the key bolt is retracted the arm 35 of the tumbler 32 will abut a shoulder 37 on thelever 37 (as said tumbler -is moved by itsspring'into lock-ing engagement relative tothe fence '31 as: thev belt Y is retracted), wherehyathe le /ver e? isi swungmpwarchsafii ciently to clear the stumps of the thumb bolts and permit a free protraction of said bolts.

In case any one of the thumb bolts is in protracted position when the key bolt is retracted, the lever 37 instead of engaging both tumbler stumps of the thumb bolts will only engage the stump of the projecting bolt, whereby such bolt will be retracted individually. In other words, the key bolt will retract either thumb bolt, or both of the same, whereby the mere retraction of the key bolt .will open the door, in spite of the projection of a thumb bolt at one side of the door, or at the other side, or at both sides.

I have not attempted to illustrate and describe the numerous modifications of the construction which may-be adopted within the scope of the claims. 1
